Kid's more than likely not done, but he's probably out of the PK game for the time being. This is Kid's Sabaody moment I guess—well, he already had something similar when Kaido showed up at his den.
ACoC is OP. ACoC with swordsman makes it an even deadlier combination.
I don't think it make it a deadlier combination just due to the fact it don't kill .
Both Zoro , BM and now Shanks use a ACoC move to KO a person .
But it was also the same for luffy every time he get KO it was with a ACoC move that KO him.
Luffy just a crazy tank where he able to tanks many ACoC moves as the fight went on .
Luffy went from getting OHKO with with 1 ACoC in beginning of wano to getting OHKO by another ACoC move on the Roof top .
To tanks many ACoC moves after he learn it him self.
